Hey now, hope everyone is well, this week went pretty good, both Glueberry OG Autos sprouted, and look good for a week in. They are currently in Pro-Mix seedling starter mixed with perlite but will be transferred to Coco Coir/Perlite as soon as their roots fill up the solo cups. I have grown seedlings in Coco Coir many times but I prefer to start them in ProMix because as there are no nutes in coco, you have to start with tiny quantities of nutes and work them up each feeding, and seedlings can be very finicky to EC/PH etc., and some strains can even be much more so than others. With Pro Mix, there is enough nutes for the first several weeks so I just give them water with a plastic syringe every 2nd or 3rd day. I have found that starting seedlings in Coir doesn't really produce a big advantage (at least for me) but her time in Coir will come.
A couple things I also do is make sure to go by container weight above all else to know when to water. It is very easy to overwater seedlings and drown them, as I did when I first started. The other thing is I just lightly water around the very edge of the cup, to prevent drowning the roots, and also to force them to work their way out to the edges of the container instead of straight to the bottom.
I started prepping a few bricks coco for this grow last night, I am re-using the coir from my last grow. I flushed it down to .4 EC and I currently have it soaking in a Cal Mag solution of 2.0 EC. I will let it soak for a few days then flush it again back down to around .4 EC. This is important to prevent cal mag deficiency down the road. To flush I just use a garden hose and a couple of saw horses with a 2X4 running through the handles of some fabric pots filled with my coir. It makes it easy to flush, and also easy to catch runoff underneath and measure the EC. I inspected and tested 2 of my drainage system this afternoon as I always test them outside with a few gallons of water before I set them up in the tent. Not much to do this week but hand water them every couple days, and hopefully by next update one of them will be ready or damn near ready for her final home which will be a 5.4 Gallon Airpot. I will be giving the other away to a friend to see what he can do with it. Once in her final home she will get fed 4x per day, and the runoff will go to my tomatoe plants outside which will also be in coir.
I am super excited to crank this Medic Grow Spectrum X up and see what she can do. I am currently running her at 30% which is about 230 watts. I will be adding more seedlings to the tent here shortly to try and fill her up, but I started with the longest autoflowers and am trying to time them so they are all ripe within a relatively close time frame. Thanks for stopping by, stay safe, and Blaze On! 💪
